I do have some complaints about the Jira web ui (in particular it seems finding correct issues can be difficult), though maybe nothing too severe.
For me the most useful thing would be a cli tool (not tui) to just add stories. This way I could just write a bunch of stories in a text file (..or an .org file..) with the conveniences of my editor and upload them. Seems jiratui actually comes with some cli tools as well, but it doesn't seem this is yet included, or it's not just documented yet. I'll give a shot to this..
Now I'm doing that by copypasting the entries from the file, one by one, to the fields in the web ui, and not all of the fields can be copy pasted, and then updating also the file to have the correct issue ids so I can use them for finding issues with e.g. grep. Naturally this will only work for my stories, and won't synchronize with changes made in Jira.
You can write your stories in csv (or vibe code a tool to do that) and then batch import the CSV.
